TLE2072AID Equivalent & Substitute Parts

Part Overview

The TLE2072AID is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) device in 8-SOIC surface mount packaging. This component is classified as a Last Time Buy product, indicating discontinued production with limited remaining inventory (3700 Pcs). The TLE2072AID operates across a wide supply voltage range of 4.5V to 38V and is suitable for applications requiring low input bias current and moderate bandwidth performance. Due to its Last Time Buy status, identifying equivalent and substitute parts is necessary for design continuity and long-term component availability.

Substitute Part Grouping Explanation

Substitute parts for the TLE2072AID are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Critical Matching Parameters:

Package / Case: 8-SOIC (0.154", 3.90mm Width) — all substitutes must use identical surface mount packaging
Mounting Type: Surface Mount — required for PCB compatibility
Number of Circuits: 2 — dual-channel configuration
Voltage - Supply Span: Minimum 4.5V to Maximum 38V — operating range must encompass or match the original specification

Performance Parameters (Allowable Variation):

Slew Rate: 45V/µs baseline; substitutes may exceed this value
Gain Bandwidth Product: 10 MHz baseline; substitutes may exceed this value
Current - Input Bias: 20 pA baseline; substitutes may have higher values within acceptable limits
Voltage - Input Offset: 700 µV baseline; substitutes may have lower values
Current - Supply: 3.1 mA baseline; substitutes may vary
Current - Output / Channel: 48 mA baseline; substitutes may vary
Operating Temperature: -40°C to 85°C baseline; substitutes may have narrower ranges

Compliance Parameters:

RoHS Status: ROHS3 Compliant — all substitutes must maintain compliance
Moisture Sensitivity Level: 1 (Unlimited) — all substitutes must match or exceed this rating

Substitutes are organized into two primary categories: direct equivalents (same amplifier type and electrical characteristics) and functional alternatives (different amplifier topology but compatible electrical performance within the application envelope).

Engineering Selection Recommendations

Primary Substitute: TLE2072AIDR

The TLE2072AIDR is the direct equivalent of the TLE2072AID, manufactured by Texas Instruments with identical electrical specifications and 8-SOIC packaging. The only difference is packaging format (Cut Tape & Digi-Reel versus Tube). This part is in Active product status with 4505 Pcs inventory available, providing immediate design continuity. Selection of TLE2072AIDR is recommended as the first choice for direct replacement.

Secondary Substitutes: J-FET Amplifiers

AD746JRZ (Analog Devices Inc.) is a J-FET amplifier with enhanced performance characteristics: 75V/µs slew rate (versus 45V/µs), 13 MHz gain bandwidth product (versus 10 MHz), and 300 µV input offset voltage (versus 700 µV). However, the AD746JRZ has a minimum supply voltage of 9V (versus 4.5V for TLE2072AID), restricting its use in low-voltage applications. Operating temperature range is 0°C to 70°C, narrower than the original -40°C to 85°C. This part is Active status with 2113 Pcs inventory.

Tertiary Substitutes: General Purpose Amplifiers

MC33078D and MC33078DT (STMicroelectronics) are general purpose amplifiers with 7V/µs slew rate and 15 MHz gain bandwidth product. These parts feature automotive qualification (AEC-Q100) and extended operating temperature range (-40°C to 105°C). Supply voltage range is 5V to 30V, which does not accommodate the 4.5V minimum of the original specification. MC33078D is available in Tube packaging (720400 Pcs), and MC33078DT in Cut Tape format (133465 Pcs).

MC1458DT (STMicroelectronics) is a general purpose amplifier with lower performance: 0.8V/µs slew rate and 1 MHz gain bandwidth product. This part is suitable only for applications with relaxed bandwidth requirements. Supply voltage range is 5V to 30V. Inventory is 1559 Pcs in Cut Tape format.

Functional Alternative: LT1355CS8#TRPBF

The LT1355CS8#TRPBF (Analog Devices Inc.) is a voltage feedback amplifier with significantly higher slew rate (400V/µs) and gain bandwidth product (12 MHz). Input bias current is substantially higher (80 nA versus 20 pA), and supply voltage range is 5V to 30V. This part is suitable for high-speed applications but not for low-bias-current requirements. Product status is Active with 50300 Pcs inventory in Cut Tape & Digi-Reel format.

Compliance and Availability Summary

All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited). Selection should prioritize TLE2072AIDR for direct replacement, with secondary options based on specific application requirements for supply voltage range, operating temperature, and performance characteristics.

Frequently Asked Questions (FAQ)

Q1: Can TLE2072AIDR be used as a direct replacement for TLE2072AID?

A: Yes. TLE2072AIDR is electrically and functionally identical to TLE2072AID. Both are J-FET amplifiers with 2 circuits, 45V/µs slew rate, 10 MHz gain bandwidth product, and 8-SOIC packaging. The only difference is packaging format: TLE2072AID is supplied in Tube, while TLE2072AIDR is supplied in Cut Tape & Digi-Reel format. Pin configuration and electrical performance are identical.

Q2: What is the key limitation of AD746JRZ as a substitute?

A: The AD746JRZ has a minimum supply voltage of 9V, whereas the TLE2072AID operates from 4.5V. Applications requiring supply voltages below 9V cannot use the AD746JRZ. Additionally, the operating temperature range is 0°C to 70°C, which does not cover the full -40°C to 85°C range of the original part.

Q3: Why do MC33078D and MC33078DT have higher inventory than TLE2072AID?

A: MC33078D and MC33078DT are general purpose amplifiers in Active product status, whereas TLE2072AID is Last Time Buy (discontinued). Active products maintain higher inventory levels to support ongoing demand. MC33078D has 720400 Pcs and MC33078DT has 133465 Pcs available.

Q4: Can LT1355CS8#TRPBF replace TLE2072AID in all applications?

A: No. While LT1355CS8#TRPBF offers superior slew rate (400V/µs) and bandwidth (12 MHz), it has significantly higher input bias current (80 nA versus 20 pA). Applications requiring low input bias current cannot use this substitute. Additionally, the supply voltage minimum is 5V, not 4.5V.

Q5: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC (0.154", 3.90mm Width) package is a surface mount configuration with standardized pin spacing and dimensions. All substitute parts listed use identical 8-SOIC packaging, ensuring PCB footprint compatibility and eliminating the need for layout redesign.

Q6: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (TLE2072AIDR, AD746JRZ, LT1355CS8#TRPBF, MC33078D, MC33078DT, MC1458DT) are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the original TLE2072AID.

Q7: Which substitute offers the best performance for high-speed applications?

A: LT1355CS8#TRPBF provides the highest slew rate (400V/µs) and is suitable for high-speed signal processing. However, this part is a voltage feedback amplifier, not a J-FET amplifier, and has different input bias current characteristics. Application-specific evaluation is required.

Q8: What is the difference between Tube and Cut Tape packaging?

A: Tube packaging supplies components in plastic tubes for manual handling and lower-volume applications. Cut Tape & Digi-Reel packaging supplies components on continuous tape for automated pick-and-place assembly. Both formats contain identical components; packaging format selection depends on assembly process requirements.
